Activity 4-5. What Is Your Parameter? Directions: Determine the parameter to be tested in each situation by writing your answer on a separate sheet of paper. Translate it into symbols. 1. The television habits of children were observed and found out that the standard deviation is 12.4 hours per week. 2. A newspaper article stated that students in the country take an average of 4 years to finish their undergraduate degrees. Suppose that you believe the mean time is longer, you conducted survey on 49 students. The result obtained a sample mean of 5 with a sample standard deviation of 1.2. 3. According to DOLE, registered nurses in government earned an average monthly salary of P9,700. For that same year, a survey was conducted on 41 registered nurses to determine if the mean salary is higher than the previous survey. The sample average was P10,000 with a sample standard deviation of P2,500.

Contingency Table

A contingency table can be defined as the visual representation of the relationship between two or more categorical variables that can be evaluated and registered. It is a categorical version of the scatterplot, which is used to investigate the linear relationship between two variables. A contingency table is indeed a type of frequency distribution table that displays two variables at the same time.

Binomial Distribution

Binomial is an algebraic expression of the sum or the difference of two terms. Before knowing about binomial distribution, we must know about the binomial theorem.
